@Olivier5,
I'm fine with the way the thumb system is, even though it is prone to abuse from time to time.
Someone who thumbs down like the recent "good thread" zero-er is quite rare, some kind of basket case on wheels.
I've been followed and thumbed down by someone or someones who don't like my views, which is, y'know, tacky, but so it goes.
We tend to use the
post thumbing system differently.
I thumb up posts that took effort: finding and providing interesting links related to the discussion, posting photographs, well written opinions (sometimes ones I don't concur with). I don't always do this, just sometimes. I thumb up for funny fairly often. I try not to thumb down for disagreement, either argue or let it be.
I do thumb down sometimes for poor internet behavior, blasting other people with insults, especially repetitively, but I'm inconsistent on that, and tend to have put those folks on ignore, or ignore anyway sans ignore button, or guiltily agree with the blaster and let it go.
Once in a while I'll see some advice as very ill advised, possibly/probably harmful if followed, usually to do with health or relationships - I will thumb down the worst of those, or speak up and argue.
On being the process being transparent, that would change the dynamic a lot and could be for the better or maybe a lot worse. I think most are bright enough to figure out that a fair amount of thumbs down re posts on threads are for disagreement and some for dislike. Would knowing who did it make you/us feel all better?
Better to slough the dandruff off your shoulders.
I'm no saint, as most of us know, so this post isn't from some high place as wise, just my thinking on the question.
